Abstract:
The present investigation on “Effect of skin coatings for prolonging shelf life of immature mangoes (Mangifera indica L.) cv. Konsam heinous of Manipur” was carried out during month of May-June of the year 2021 at Post Graduate Laboratory, Department of Horticulture, College of Agriculture, Central Agricultural University, Manipur. Freshly harvested uniform sized mango fruits were selected, washed, cleaned and treated with different coatings viz. castor oil(T1), palm oil(T2), coconut oil(T3), mustard oil(T4), aloe vera gel(T5), paraffin wax(T6), cling film(T7) and no- coated(T8) in laboratory. The experiment was framed in CRD (Completely Randomized Design) and repeated 3 times with 7 treatments and an uncoated treatment. The results obtained from the current investigation indicated that fruits treated with cling film (T7) recorded significantly lowest physiological loss in weight, specific gravity and marketability with a highest sensory quality during 12-15 days of storage, whereas the fruits coated with paraffin wax (T6) also recorded maximum retention of marketability with minimum spoilage and maximum shelf-life up to 15^th days of stored under ambient condition.
